There are a few northern sections I would change for weekday rush hour travel or for a less experienced rider but you should be fine but at Park Heights and Falstaff pick up my route http://www.bikely.com/maps/bike-path/Home-City-Hall and take Baltimore St or Pratt St into Paterson Park (If you are comfortable on Baltimore stay there otherwise drop down to Pratt as there is very little traffic as you near the park.) Note: Use hybrid mode and look closely at the route between Falls and University as it is a bit convoluted but since you are climbing out of the stream valley the residential streets are nice (and a bit less of a slope) and there is a cut through the Rolland Water Tower Park (looks more like a castle turret) a left and a right turn that is almost a u turn onto University.
